dasherize, underscored etc. using 1 uppercased char inside

[kof]

How should such string be dasharized or underscored: "GuessALike" or "GuessAlike". Currently both of variantes will lead to "guess-alike" and "guess_alike".

1. What is actually the right camel case?
2. There should be a difference between strings after transformation.

What version are you on? With 2.3.0, I get:

_('GuessALike').dasherize();
"-guess-a-like"
_('GuessAlike').dasherize();
"-guess-alike"

This should have been fixed in #89.
